White Screen upon Completion

Post by droggenbuck »

I have followed the guide and upon turning on the device, I only see a white screen. It is not the blue/white screen, and I tested it with several different PCBs and other displays. Any thoughts?

Mine too! It worked for a while and now it only shows a white screen after I made it.

White Screen when turned on

Post by SeveralPies »

After I completed the Raspiboy whenever I turn it on, the screen goes white. I plugged and unplugged the LCD connectors many times, but it doesn't make a difference. What is going on?

Hey guys,
The white LCD was so far the results of the LCD ribbon being teared. Can you check if your LCD ribbon is broken?
If not then maybe it's a defect with new v1.3

Bonjour / Hello

Tout d'abord merci pour la campagne et le projet ;)

pour en revenir au sujet, j'ai cet affichage au démarrage /
Same here, I have a display issue on start :

J'ai démonté l'ensemble, vérifié le ruban, je n'ai pas observé de "déchirure", tout remonté, même écran
I have disassembled, check the LCD, didn't observed any rip, reassembled it, still the same screen.


Cdlt,

KL

Hi again

I've checked the troubleshooting page, none of the potential explanations could help me to solve the issue

I've taken some pics, maybe you will see something I don't

@KevinL Can the unit boot on HDMI? If it can't boot on HDMI please test the raspberry pi zero alone on HDMI. If it can't boot then the problem comes either from the pi it self or from the SD card.

Please let me know
